The owner of one of the region's largest construction material companies wants to develop two waterfront parcels in South Troy — including the vacant Bruno Machinery building on the Hudson River.

The plan by Roddy Valente of R.J. Valente Gravel of Waterford brings together efforts by the City of Troy to redevelop the former Scolite Roofing site on Madison Street, which the city owns.

R.J. Valente was one of several companies to respond to a request for development ideas from the city for the Madison Street site, which has a minimum bid of $125,000.

A city official couldn't immediately be reached for comment.

Valente said Thursday that he bought the Bruno Machinery site to the south, which borders Madison and Monroe streets, to enhance his bid with the city to develop the Scolite site.

Valente says his plan is to turn the two parcels into a transportation center where he ships and receives construction materials. The Scolite site has space where barges could be docked, and the property is bordered on the east by a CSX freight rail line.

Valente also plans a walking path along the Poestenkill, as well as a picnic area and a boat launch at the Bruno site, which has a 150,000-square-foot warehouse.

The Bruno property had been owned by Troy developer Sandy Horowitz. But Horowitz has been selling off his local properties, many of them landmarks, to satisfy creditors as part of a Chapter 11 bankruptcy reorganization plan. Horowitz had recently told a federal bankruptcy judge that he has a contract to sell the Bruno property for $750,000, although at the time the buyer had not been revealed.

In addition to the R.J. Valente gravel, stone and trucking businesses, Valente is also a real estate developer. He says that the Bruno and Scolite sites, which total 10 acres, could have the potential for 80 jobs if redeveloped under his plan.
